The Richards
Double Tube
Angle
Thermocouple
Assemblies are designed for severe service applications. The double
tube
assemblies
with a
metal
outer tube
are
for
applications
where
mechanical
damage and thermal
shock
to the thermocouple
is
a
prob-
lem.
The double tube angle assemblies,
which
have a Silicon Carbide outer
tube,
are for applications where thermal shock and flame
contact
is
a
problem.
Double ceramic
tube
angle assemblies are
for extra
protection against
corrosive atmospheres. We offer
many
other combinations of double tubes, which we could not list
in
this catalog due to space
limitations.
Richards double tube angle assem-
blies
can be
made
from
any
type of
metal or ceramic
tube, which
is available.
Note:
If

just
substitute
the
